matplotlib-users Mailing List for matplotlib

hi jessica, thanks.... So scipy.optmizer as it stands cannot do that? I 
gues I should move the issue to the scipy list then. Yes there is mpfit, 
there is also pyminuit in google.code that is wrapper of the high energy 
physics standard package MINUIT, etc.... but I would think that fitting 
data, with fixed/thawed parameters, is a basic feature of a scientific 
package. As there seems to be a snergy between matplotlib and scipy, I 
would expect the latter to take care of optimization....
thanks for the replies,
Johann

John,
Yes, thank you. That did the trick. I did setuptools. I guess 
EasyInstall is another package build on that.

Tony: There is a hidden dependency on the setuptools module in basemap 
0.9.8. This will be fixed in 0.9.9, but in the meantime you can just 
install setuptools (http://python.org/pypi/setuptools).

It looks like you need to install setuptools:
http://peak.telecommunity.com/DevCenter/EasyInstall

Is there a new version of this which uses numpy instead of Numeric? I found
the old Numeric version to work very well.
cheers,
William

I tried to install basemap 0.9.8 on an OS X system (PPC, 10.4.10), 
after installing matplotlib from the latest binary package (0.91.1). 
I receive the following error:

It seems that the dap package did not completely install. Is there a 
directory I should add to my sys.path? Thanks for your help!

Hi Johann,
I would recommend using the python mpfit module:
http://cars9.uchicago.edu/software/python/mpfit.html

Thanks for the bug report. This is now fixed in svn. I suspect similar
bugs may lurk in a few other axes methods; I have not checked for them.
